SLEDGE.

To all whom it may concern:

Be it known that I, J ULIUS LIcHTENsTmN, a subject of the GermanEmperor, and resident of 38 Scharnhorststrasse, Leipzig, Germany, haveinvented certain new and useful Improvements in and Relating to Sledges,of which the following is a specification.

The object of my present invention relates to a sledge and its newfeature consists therein that the same is provided with a drivingmechanism by means of which the sledge can be driven by the personcarried by the same without using any other power as e. 9. horses, humanbeings, or the like. This arrangement of course considerably increasesthe effect of the sledge.

In the accompanying drawing in which I have illustrated the nature of mysaid invention like letters of reference refer to like parts throughoutthe different views.

In said drawings, Figure 1- shows a side View of my improved sledge, andFig. 2 shows a section according to line I-I of Fig. 1. Figs. 3 and 4show details of Fig. 1.

The outer appearance of the sledge resembles a bicycle and it consistsof a frame a the rear part of which preferably provides two pairs ofsupporting rods 22 and c to which the sledge runners are fastened bymeans of screws. The supporting bars 0 provide a bearing for a shaft 9having several oppositely directed cranks f. Pivotally fastened to saidcranks f are levers k serving to drive the sledge by means of their projections i being provided on their lower surface with pointedexchangeable teeth It or the like and having the form of shoes. Theselevers 7c are continually pressed down upon the bottom by means ofspiral springs Z which are at one end connected to the frame a and atthe other end to the slid- Specification of Letters Patent.

ing pieces m of the levers is. Inside the spiral springs I preferablyarrange telescopingly working rods n in order to attain an even workingof said springs. The driving of the shaft 9 is effected by means of thechain wheel transmission 0 which is caused to rotate by means of pedalsMounted upon the upper cross bar of the frame a is an adjustable saddleg.

The steering of the sledge is effected by turning the rod 8 mounted in avertical bearing of the front part of the frame and carrying thesteering bar t on its upper end. At its lower end said rod 8 isconnected to a bar it having the shape of a sledge runner.

In the present construction the frame is constructed for gentlemandrivers but it can just as well be constructed for lady drivers.

What I claim as new and desire to secure by a United States LettersPatent, is 2- In a bicycle like driven sledge the com bination of acrank shaft mounted in bearings of the frame, several levers pivotallyfastened to said cranks, sliding pieces freely sliding on said levers,telescopically mounted tubes connecting said sliding pieces to the upperpart of the frame, spiral springs surrounding said tubes adapted tocontinually press said levers against the floor, shoe like projectionson said levers, located at. their lower free ends, and detachable teethfastened to the lower surface of said rojections, substantially asdescribed and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 20th day ofOctober, 1908, in the presence of two subscribing witnesses.
